weird electrical/charging problem?
Engine just wont run good with alternator charging, or just running pcm above 13v or so?
The big wire burned off the alternator and tune is perfect that way at 11v, without alternator charge.
I put another alternator on and same shit tune, runs 14+v and pcm tune is shit.
My Cen-tech meter shows very little ac output on the big wire. i think it was no more than 0.7VAc
i checked a different alternator on a running VW and it showed 0.2-0.3VAc. too much ac? if so why? diodes?
also sometimes while driving along "all of the sudden" it sounds like someone started welding on rusty steel inside my ear drum.WTF
sounds like huge static is flying around the roof of car LOL. its not the speakers or head unit.
anyone here got a brain that can help me?
